H.R. McMaster dodges questions when asked about Steve Bannon

Trump's national security adviser, H.R. McMaster, repeatedly dodged questions on Sunday when NBC's Chuck Todd pressed the lieutenant general on whether he and Steve Bannon can work in the same White House.

From former chief of staff Reince Priebus to Trump's senior adviser and son-in-law Jared Kushner, reports of Bannon -- who previously ran the nationalist Breitbart website -- butting heads with others in Trump's inner circle are nothing new. Latest internal descriptions of White House culture describe Bannon as at odds with McMaster, and Anthony Scaramucci hinted on Sunday that Bannon's days as the White House chief strategist might be numbered.

During a "Meet the Press" interview, Todd asked McMaster about this reported drama three times, and three times McMaster refused to answer.
